What part of the cell uses amino acids to build proteins?
All cells synthesize (build) proteins from amino acids. The information that the cell needs in order to arrange the amino acids in the right sequence is stored in DNA.
Are all amino acids reactive with the Biuret reagent?
Not all amino acids react with the Biuret reagent. The Biuret test specifically detects the presence of peptide bonds, which are formed when amino acids link together in proteins. Therefore, free amino acids without peptide bonds do not produce a color change with the Biuret reagent. However, when amino acids are part of a polypeptide or protein, they will react positively with the Biuret test.
What part of a ribosome catalyzes the formation of peptide bonds between amino acids?
The peptidyl transferase center (PTC) of the large ribosomal subunit catalyzes the formation of peptide bonds between amino acids during translation. This center is responsible for joining the amino acid chain to form a protein.
What type of chemical grouping present in all proteins?
A protein is any chain of amino acids. An amino acid is a small molecule that acts as the building block of any protein. If you ignore the fat, your body is about 20-percent protein by weight. It is about 60-percent water. Most of the rest of your body is composed of minerals (for example, calcium in your bones). Amino acids are called "amino acids" because they contain an amino group (NH2) and a carboxyl group (COOH) that is acidic. In the figure above, you can see the chemical structure of two of the amino acids. You can see that the top part of each one is the same. That is true of all amino acids -- the little chain at the bottom (the H or the CH3 in these two amino acids) is the only thing varying from one amino acid to the next. In some amino acids, the variable part can be quite large. The human body is constructed of 20 different amino acids (there are perhaps 100 different amino acids available in nature).
What is the digestive juice that breaks down protein into amino acids?
The digestive juice that breaks down protein into amino acids is called pepsin. Pepsin is produced by the stomach and helps to break down proteins into smaller peptides and amino acids, which can be absorbed by the body.
What part of the cell uses amino acids to build proteins?
All cells synthesize (build) proteins from amino acids. The information that the cell needs in order to arrange the amino acids in the right sequence is stored in DNA.
Amino acids that are not yet part of a polypeptide are found in which part of the cell?
Amino acids that are not part of a polypeptide are typically found in the cytoplasm of a cell. They are either freshly synthesized by ribosomes or recycled from proteins that have been degraded.
Are all amino acids reactive with the Biuret reagent?
Not all amino acids react with the Biuret reagent. The Biuret test specifically detects the presence of peptide bonds, which are formed when amino acids link together in proteins. Therefore, free amino acids without peptide bonds do not produce a color change with the Biuret reagent. However, when amino acids are part of a polypeptide or protein, they will react positively with the Biuret test.
Which cell part is directly involved in the bonding of amino acids to form proteins?
The two parts of the ribosomes come together to transform amino acids into protiens.
Is polypeptide an amino acid?
No, a polypeptide is not an amino acid. A polypeptide is a chain of amino acids linked together by peptide bonds. Amino acids are the building blocks of proteins and are the individual units that make up a polypeptide chain.
What part of a ribosome catalyzes the formation of peptide bonds between amino acids?
The peptidyl transferase center (PTC) of the large ribosomal subunit catalyzes the formation of peptide bonds between amino acids during translation. This center is responsible for joining the amino acid chain to form a protein.
Are amino sugars part of amino acids?
no amino sugars are not part of amino acid
In what part of the cell is tRNA found?
tRNA is in the cytoplasm where it picks up amino acids and takes them to the ribosomes during translation.
What is the importance of native amide bonds?
Native amide bonds take part in formation of a peptide. If the amine and carboxylic acid functional groups in amino acids join together to form amide bonds, a chain of amino acid units is formed, thus called the peptide bonds.Ê
What are the buliding blocks of proteins?
Amino acids make up all proteins. The human body can make most amino acids, but the "essential" amino acids must be take in in as part of the diet for normal body function. Protein synthesis takes place in the ribosomes and is directed by a cell's DNA.
What part does proteins get digested into?
Amino acids.
What cell process is the vacuole a part of?
The vacuole is part of many processes in plants. These processes include osmoregulation, storing amino acids, managing the homeostasis of cell ph and other degradative processes.
